.made of metal and closed by a spring All.y The; nipple 38 is formedlfor the attachment of e union 42 whereby an outlet pipe 43 severalpipes 43 are .all connected to a collector pipe 44 which surrounds theframe pipes being preferably.

member 14, these razed so'that they will be sulliciently supportedvbythe cylinders5 A pipe 45, preferably made of yflexible material,'conducts the compressed air from the collector pipe to the valve stemof the tire, a suitable coupling 46 being provided for making.connection with tbc valve stem.

, When the compressor is attached to a rotating Wheel every part thereofrotates with the wheel, with, the exception of the Weighted arm andcrank. The resistance of the air being compressed in the cylinderscauses the Weighted A perpendicular, partly by the location of thereference to its`fulcrum 2'6.`

' be developed vmay be varied by changing tbe 1 ports 31 which admit itcad ustment of the Weiffht'on the'arm these- .l e; a

ries of holes being provided for this purpose. The volume of air whichis compressed is limited by the capacity of the into the cylinders.Consequently, the Weighted erin, if suliciently weighted to' compress'the maximum volume,v lWill not be thrown over its ulcrum byexcessivespeed of rotation of the Wheel, because the volume of airadmitted def creases as the 4excess of speed increases,

' Therefore the restriction of voluniecompensatcs for an restriction inthe of time of a compressing stroke.'

The eine va the'4 compressor as length luegof means for inletingl atireupon a rotating Wheel is that it can beused to furnishl acontinl1ous-supply"ofair for a punctured, end-thus enable the vehicle toproceed to a. repair shop :Without rim-cutting thev tiren or Withoutincurring other inconveniences dige to e deflated tire.' If it isdesired to inflate a tire While the vehcleisstanding, the pistons may beopcratedby turning the ar1n25 by'meensofthe-hlandle 50. Thevveiglitwould better be .removed when the arm Is operated-manually. v

When the compressor is'ope'rated by the WeightaQS, and rotation 4of theWheel, Vit becomes inoperative automaticallyl When the reaches apredetermined v degree. This degree is determined by the t pressure inthe tire is connected. rlhev -1n which arm to assume en 'angle tothewhich -angle is determined Weight with As the yerin moves away from theperpendicular its enfA pressure-'which ln'ay tire which lis 'signature,

vehicle is sub'ected to vibration :due to to indicate that the maximumpressure is reached. l Having thus explained the natureofany saidinvention ind described a Way of constructing and using the same,although without attempting to set forth all the forms it may its use,what I claim is:"

1. An air compressor comp a pistonfor cooperating With said cylinder tocompress air, a crank connected tosziid piston to reciprocate the same,means crried by the Wheel for affording a bearing for said crankparallel'to thefwlieel axis, said era-nk being Weighted so as to remainsubstantially in one position While the cylinder rotates with the Wheel,end an air conduit for connecting the \cylinder With pneumatic tire onsaid Wheel. v

2. An sir compressor comprising e frein'x adapted to be affixed to aWheel, a cylinder affixed to said frame, a piston for coperating withsaid cylinder to compress eine crank connected to said piston toreciprocute the same, said crank having e, bearing inl seid freineyparallel tothe Wheel axis, said crank being Weighted so es t0 be heldagainst rotation when said frame protates, ,and an air conduit forconnecting the cylinderwitli a' pneumatic tire on said Wheel.

3. The combination pneumatic tire thereon, of a cylinder atl'ix'ed tosaid Wheel, a piston Jarranged to .cooperate With `said cylinder tocompress air, a crank connected to said piston to reciproaxis, saidcrank being weighteclfso es to be held agai' 't rotation whenitsfbearing supporti'o'tates with the Wheel, and yan air conduit forconnecting said cylinder and tire.
